Of course, lithium-ion batteries are wrong, such as high prices and provide discharge less, and so on. Only the number of lithium batteries provide 400-600 discharge times, but also through special improvement products 800 times. By charging a daily basis, but also the best lithium batteries for more than two years. And nickel-hydrogen batteries charge number to reach 700 or more, some good quality products made discharged to 1200 times, such a comparison, the nickel-hydrogen batteries longevity than lithium batteries, nickel hydrogen batteries and lithium batteries lower than prices. In view of this, there is as yet no perfect notebook batteries.
Common brand for the vast majority of notebook batteries folk. Markets have a small number of normal cells Chaobo notebook use, such as the Sony 505 series, Toshiba protege series. Cell materials and models based on the weight change, such as the shape of the same capacity and nickel hydrogen and lithium call, but a lot of weight.
Capacity primarily from the size indicated mAh battery to judge its Chinese name is milliampere. Milliampere-hour notebook size is directly related to the use of time, but also can not be generalized. The use of time with notebook battery configuration has a lot to do with, for example Well, Hewlett-Packard 6100 notebook introduced PIII-M, Mobility Radeon Xianqia many energy-efficient technologies such as hardware, with 4000mAh batteries, the use of time-four hours. Using the desktop CPU Toshiba 1800, although equipped with 4500mAh batteries, the use of time can only reach three hours. Working to meet the general needs. It also showed the notebook to use the time not only with mAh batteries, hardware energy-saving technologies is very important.
Second, notebook batteries - new technologies
The battery is achieved through mobile notebook computers from desktop office an important feature, and limited battery capacity, unlimited use of time to meet requirements of the growing notebook computer hardware configuration for battery consumption is also growing, and notebook computer batteries from lithium batteries are still not widely used after the major breakthrough to meet the growing power consumption, and to guarantee the use of time, then some of the new energy-saving technology becomes very important

How to notebook computer battery charging?
There is also a need to have a good conductive nature, reduced battery internal inertia.
Although lithium-ion batteries are nickel-cadmium batteries little memory effect, the theory is the crystallization of memory effects in almost lithium batteries will not have such a response. However, lithium-ion rechargeable batteries in several capacity will decline after release, the reasons are complex and varied. Mainly negative electrode material itself is changing, from the molecular level, is the negative electrode of a lithium-ion accommodate structure will be gradually 18th hole, plug; From the perspective of the chemical is being cathode materials reactive passivation, a deputy response generated stable other compounds. Physics, material will gradually falling off as a positive situation, in short, can ultimately reduce battery provides free discharged in the course of the lithium-ion mobile number.
An overcharge and excessive discharge will be lithium-ion batteries are cathode caused permanent damage, from the molecular level, can intuitive understanding will lead to excessive discharge of carbon cathode excessive release lithium ion and make their films at the structural breakdown, excessive charging will be too much lithium ion hard into the structure where the carbon cathode, and lithium ion no longer makes some release. This is why normally equipped with lithium-ion battery provides discharge control circuit causes.
Unsuitable temperature will trigger internal lithium ion battery other chemical reactions generated We do not want to see the compounds, so in many lithium ion batteries are negative electrode temperature divide between a protective or electrolyte additives. In some cases the cells warming, composite membrane electrolyte membrane Kong closed or degenerative, batteries internal inertia increased until open circuit, the battery no longer warming, ensuring battery charging temperature normal.
And lithium-ion rechargeable battery or can upgrade the actual capacity? Experts clearly told me that this is meaningless. They even said that the so-called three-person before use on the "back" in their knowledge of the two Dr., also can not imagine what it necessary. But why many people leave after dark place in Battery Information marker capacity will change? Will be mentioned later.
IBM notebook computer with a lithium-ion battery charging control chips and management chips. These chips are a series of register management, a capacity, temperature, ID, the charging state, the number of discharge values. In the use of these values will gradually change. I personally think thatcom IBM notebook puters in use on the "whole person should use a month later on a" practice is the main role should be to amend the register of improper value, making battery charge control and the actual nominal battery capacity coincide.
Charging the battery charging control chip main control process. ThinkPad lithium-ion batteries charging process is divided into two stages, Hengliu provides fast stage (a yellow battery light) and Hengya current decline phase (a battery light green lights. Hengliu Express provides stage battery voltage batteries gradually rise to the standard voltage, and then in the control chips into Hengya stage, voltage not been made to ensure that no longer rise, with the current battery consumption to rise gradually weakened 0, and the final completion of charging.
Statistics chip sales through the records discharge curve (voltage, current and time) can be calculated sample cell capacity, and that is what we read in the Battery Information Lane Estate. Values. And lithium ion batteries used in numerous after discharge curve will be changed, if the chip had not had the opportunity to once again read out a complete discharge curve, the calculated amount is inaccurate. So we need to take a deep cover calibration cell chip.
Finally, I think the maintenance of the batteries :
1. Not deliberately guarantee every person to have the power to take End;
2. Time to do a deep-protection circuit provides controlled release of power to amend batteries statistics, but it will not enhance the actual capacity of your batteries.
3. Long-term idle batteries to be placed on the shady places to weaken its own internal passivation reaction speed.
4. Protection circuits are also unable to control cell self discharge, the batteries do not have long-term, should be made into a certain amount of storage in order to prevent the batteries from over-discharge led to the discharge of excessive damage.
In fact, not too many have to take into account the use of batteries attention, in other words taking into account also is not much use. How many times a cell can use, perhaps more differences from the manufacture of individual differences cell itself, rather than using methods. Choice of a good reputation in the notebook computer brands, the use of long-life batteries is the one of the guarantees.

Notebook computer battery selection reference!
Notebook computer battery life-like no more than three to four years, it is perhaps the most likely users of the replacement things. Two years after the use of notebook computers will be found in an increasingly fast battery consumption. Possible, the old batteries can be replaced by new cells to ensure the stability of the computer.
When in need of replacement notebook computer batteries, preferably with a selection of models to replace batteries. But if the old computer is used nickel-hydrogen batteries, battery power supply for much longer, of course, can be designated as computer users manual or manufacturers recommended models use lithium batteries. Although nickel-hydrogen batteries are inexpensive, but the existence of memory effect, but in the same capacity under weight than lithium batteries, and large lithium batteries have no memory effect, lightweight, long time, such as electricity merits notebook computer battery has become the standard configuration. This notebook computer manufacturers use lithium batteries because of the different time in power there a certain gap between friends should be noted in the purchase process, the distinction between different brands in the cell, a comparison between the best of several brands.
In addition to the performance indicators battery manufacturers stated supply time, we also need to pay attention to their capacity. Battery capacity is usually AH (ampere-hour, ampere hours), with the most current notebook computers around 4000AH, but ordinary cell can be sustained two hours. In addition to the time of the battery power of computers with heat release sexual energy and other factors, screen size (the greater the consumption), screen brightness, and the implementation of the work have an impact on the supply time.
Now notebook batteries in 1000 at ocean bottom, about the price of the overall notebook 10%- about certain Chaobao aircraft even higher. And battery warranty period, the Bulgarian three months, six months of insurance, but also the longest one; The batteries warranty time is extremely short because notebook batteries consumables, charging frequency is constant, with a small one. Moreover, notebook batteries and other hardware are different, there is no room for repairs can only be broken. For such products lengthy warranty (proven), the invisible, the burden on manufacturers increased, the purchase notebook, some asked about the warranty time and battery conditions. Also in the purchase of second-hand notebook computer time also try not to forget its aircraft batteries to ongoing work within the length of time. Normally used in 1912 after the notebook computers in sufficient electricity, nickel-hydrogen batteries can support some computer work one hour or so, lithium ion batteries can support nearly three hours, but compared to the new cell, which is very low demand, can not achieve this target on the description of spent batteries from a corner.
